我试图让我的按钮改变他们的文本的颜色，当它是pssed $ P $，但我跑成我不能解决的问题。我得到一个错误说无法解析颜色值，那么它​​给我的文件路径。这里是我的文件使用im

I am trying to make my buttons change the color of their text when it is pressed but i ran into a problem that i cant solve. I get an error saying "unable to resolve color value" then it gives me the path to the file. here are my files im using

这一个是在一个新的文件夹命名颜色的资源之下，其所谓的按钮

This one is in a new folder named color under resources and its called button

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:color="#ffff0000" />
<item android:state_focused="true" android:color="#ff0000ff" />
<item android:color="#ff000000" />
</selector>

和

<Button android:text="Main Menu" android:textColor="@color/button"
    android:layout_width="200px" android:id="@+id/mainmenu"
    android:layout_height="55px" android:layout_x="5dip"  
    android:layout_y="174dip"
    android:textSize="18px">
 </Button>

其驾驶我疯了，如果有人可以帮助我。

its driving me crazy if anybody could help me.
